Abstract Background Understanding the relationships between physical fitness characteristics and sports injury may assist with the development of injury minimisation programs. The purpose of this systematic review was to investigate the association between physical fitness attributes and sports injury in female, team ball sport players. Methods Four scientific databases (MEDLINE, EMBASE, SPORTDiscus, Scopus) and reference lists of relevant research were searched for eligible studies up to September 2, 2019. Full-text articles examining the relationship between physical fitness and sports injury in female, team ball sport players were included. A modified Downs and Black checklist was used to assess methodological quality. Data synthesis determined summary conclusions based on the number of significant relationships divided by the total relationships investigated and reported as a percentage. Level of certainty was identified for summary conclusions based on level of evidence. Sub-analyses regarding competition level, age, and single injury types were also conducted. Results A total of 44 studies were included. Data synthesis revealed no associations (low to moderate certainty) between body composition (1/9; 11%), flexibility (18–20%), and balance (2/8; 25%) and ‘any injury’ classification. No associations (mostly of moderate certainty) were found between flexibility (0–27%), muscular strength (0–27%), and body composition (14–33%) and various body region injury classifications, whereas mixed summary conclusions were shown for balance (0-48%). Many associations between physical fitness and sports injury were deemed ‘unknown’ or with an insufficient level of certainty. Sub-analyses revealed no association between strength and noncontact ACL injuries (0/5; 0%) or ankle sprains (0/12; 0%), and between flexibility and ankle sprains (1/5; 20%); however, insufficient certainty of these results exists. Clear associations were concluded between balance and lower body injuries in female, non-elite (10/16; 63%) and junior (9/12; 75%) team ball sport players, with moderate and insufficient certainty of these results, respectively. Conclusion Limited evidence is available to demonstrate relationships between physical fitness and sports injury in female, team ball sport players. High-quality evidence investigating the multifactorial nature of sports injury, including the interactions physical fitness qualities have with other injury determinants, is needed to better understand the role of physical fitness in minimising sports injuries in female, team ball sport players. Trial Registration CRD42017077374 (PROSPERO on September 14, 2017).

ABSTRACT Objective: To synthesize the evidence available in the literature on the relationship between the components of physical activity, physical fitness and academic achievement in adolescents. Methods: The review followed the methodological procedures described by PRISMA and was carried out in the Lilacs, Medline, SciELO, PubMed, Web of Science and Science Direct databases. Quantitative empirical studies published as of 2006 were included. The following descriptors and keywords were used: “Motor activity”, “Physical fitness”, “Physical activity”, “Educational status”, “Academic achievement”, “Academic performance”, and their equivalents in Portuguese and Spanish. Results: The most widely investigated variable was physical fitness (45.5%) followed by physical activity (40.9%), whereas only three studies (13.6%) investigated both. Conclusion: Physical activity and physical fitness are positively associated with the academic achievement of adolescents. In more than 80% of studies the association was considered strong. The physical fitness component most frequently associated with academic achievement was cardiorespiratory fitness. Level of evidence II; Systematic review.

There is a growing interest in knowing the relationship between biological maturation and sport performance-related variables of young athletes. The objective of this study is to analyze the relationship between biological maturation, physical fitness, and kinanthropometric variables of athletes during their growing period, according to their sex. The systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement and the search protocol was registered in PROSPERO, code: CRD42020208397. A search through the PubMed, Web of Sciences, and EBSCO databases was performed. A total of 423 studies were screened and 13 were included in the meta-analysis. The meta-analysis was completed by using the mean and standard deviation of each variable according to each maturation status (early, on time, or late). Differences depending on maturation were found on physical fitness, with better results in the advanced maturational groups in the male population (standard mean difference (SMD) = 0.17–2.31; p < 0.001–0.05). Differences depending on maturation were found for kinanthropometric variables in males (SMD = 0.37–2.31; p < 0.001–0.002) and height and body mass in females (SMD = 0.96–1.19; p < 0.001). In conclusion, the early maturation group showed higher values in kinanthropometric variables and better results in physical fitness, highlighting the importance of the maturational process in the talent selection programs. Despite that, more research is needed to clarify the relationship of maturation with the other variables on female populations and the changes in the muscle and bone variables during the maturation processes of both sexes.

El objetivo de este estudio fue identificar el panorama científico con respecto a los estudios con entrenadores de balonmano. Para esto, se realizó una revisión sistemática con búsquedas en diferentes bases de datos desde el año 2000. El análisis de los artículos seleccionados permitió identificar tres temas: a) intervención de los entrenadores para el desempeño; b) intervención de entrenadores centrados en aspectos psicológicos; y c) perfil y formación de entrenadores. Los artículos analizados destacaron la formación de los entrenadores, teniendo como temas principales abordados por los investigadores las intervenciones de los entrenadores relacionadas con los contenidos técnico-tácticos, los comentarios, la preparación física, las formas de liderazgo y la relación con los jugadores. Se concluyó que los estudios con entrenadores deben ser estimulados para ayudarlos en el proceso de aprendizaje profesional, pero también se debe dar más énfasis a las categorías iniciales de entrenamiento deportivo, ya que se encontró preferencia por artículos que retratan la categoría de adultos. The aim of this study was to identify the scientific scenario situation of the handball coaches. For this, a systematic review was performed with searches in different databases since 2000 in three specific themes: a) coaches intervention in performance; b) coaches intervention in psychology issues; and c) coaches profiles and formation. The analyzed papers highlighted the coaches professional learning, and the mainly investigated subjects were related to the coaches’ interventions related to the technical-tactical contents, the feedbacks, the physical fitness, the leaderships ways and the relationship with players. It can be concluded that studies with coaches should be stimulated to assist them in the professional formation process, but greater attention should also be given to the youth sports, once that was found a preference for works involving adult teams.
